Sprinkler irrigation, with its adaptability and effective control of water application, is used for irrigation fields of all kinds of soils on varied terrain. It is necessary and feasible to develop the sprinkler irrigation in mountainous and hilly areas where irrigating is difficult because of varied terrain, and in sandy soil areas where serious loss is caused by its percolation, and in districts where there are deep wells with very insufficient water resources.

Sprinkler irrigation, with its adaptability and effective control of water application, is used for irrigation fields of all kinds of soils on varied terrain. It is necessary and feasible to develop the sprinkler irrigation in mountainous and hilly areas where irrigating is difficult because of varied terrain, and in sandy soil areas where serious loss is caused by its percolation, and in districts where there are deep wells with very insufficient water resources. It plays an active part in improving shortage of water resources in Hebei province and is of practical significance in raising agricultural production in the abovementioned areas.

This is a case study of the Weibei dryland irrigaton project in the eastern part of Guanzhong of Shaanxi Province. In this case study, two alternative plans of how to use irrigation facilities with and without land levelling were examined. The economic evaluation of enviromental effects caused by each plan was made. In our analysis, the replacement cost, shadow project and penalty approach were employed. In the land-levelling case, three different land-levelling patterns (i.e.shaving head, ditching and...

This is a case study of the Weibei dryland irrigaton project in the eastern part of Guanzhong of Shaanxi Province. In this case study, two alternative plans of how to use irrigation facilities with and without land levelling were examined. The economic evaluation of enviromental effects caused by each plan was made. In our analysis, the replacement cost, shadow project and penalty approach were employed. In the land-levelling case, three different land-levelling patterns (i.e.shaving head, ditching and reeling) were examined, In addition, the various discount rates were used to calculate their present values. The results obtained from the case study indicate that it is economically feasible to carry out the land-levelling plan, and reeling is the most desirable method among the three patterns.

本文是有关陕西关中东部渭北旱原区灌溉计划的个案研究。该项研究中,对如何利用灌溉设施的两种可供选择的计划——平整土地和不平整土地,进行了考察,并对采用每种计划所引起的环境效果进行了经济估价。分析中采用了替代成本法、影子工程法和罚款法。在分析土地平整计划时,考察了推光头、拉条子、倒桄子三种不同的土地平整方式。此外,利用不同的贴现率计算了两种计划的现值。个案研究的结果表明:采用土地平整计划是经济有效的。而在三种不同的平整方式中,倒桄子是最优的。

The comprehensive utilization of River Pei, Shi, and Hang, the three-river area, in Anhui Province was a waster conservancy project including irrigation, electrity navigation and cultivation etc. It was an artificial ecological system, but Some ecological disasters occured in that place currently. Besides [adopting the policy of general help to the people there, the local government should also make ecological compensation such as afforestation in the mountainous districts.The funds for ecological compensation could be made from the charges from water conservation for irrigation, from protection of water resources and generation of electricity from the reservoirs, and from exploitation of water resources for industry and living. The funds could also come from the charges for flood protection, from Water and soil conservation extended by the state and from the money delivered to the old revolutionary bases as subsidy and also from the exoloitation of other resources in the mountainous districts.The distribution of the funds for ecological compensation should be closely connected with the conditions of forest management, adopting the policy of providing work as a form of relief and aconomic contracts to bring full play of the initiation of the people in planting and protecting forests, so as to keep high level of ecological balance.

安徽省淠史杭沟通综合利用工程,即淠史杭灌区是灌溉、发电、航行、养殖等多功能水利工程,是一个人工生态系统。如今,有些地方出现了生态失调现象。 国家对那里的群众除采取一般性扶助政策外,建议还应对山区森林植被实行生态补偿。 生态补偿资金的来源以灌溉用水的水源涵养费,水库发电的水源保护费,工业、生活用水的水资源开发费,环境净化费,防洪效益费,国家下拨的水土保持费,包括老区补助在内的财政专项拨款和山区其它资源开发返偿费。 生态补偿费的发放应同树木管理的好坏紧密结合起来,实行以工代赈、经济承包的措施,充分发挥山区群众造林、管理(护林)积极性,使整个生态系统维持在一个高水平上的平衡。
